Brief Summary

The aim of this study is to identify the factors associated with successful rehabilitation following hip arthroscopy for femoroacetabular impingement syndrome and to highlight any persistent functional deficits at different key stages of rehabilitation. This is a controlled multi-observational study. The pathological hip of patients will be compared to their second healthy hip as well as to a healthy control group. Assessments of mobility, strength, functional tests, and questionnaire submissions will take place before the intervention and 3 and 6 months after the intervention.

Femoroacetabular Impingement Syndrome; Healthy Participants

Femoroacetabular impingement syndrome; Physical impairments; Questionnaires; Strength; mobility

Outcome Measures

Primary Outcomes (6)

• Muscle strength in Nm

  Muscular strength is measured using a fixed dynamometer

  Pre-intervention, at 3 months and 6 months post-intervention

• Hip mobility in degree

  Hip mobility is measured using an electronic goniometer

  Pre-intervention, at 3 months and 6 months post-intervention

• Functional results on the Y Balance Test

  The functional results of the Y balance test will be measured using the composite score.

  Pre-intervention, at 3 months and 6 months post-intervention

• Functional results in the single-leg squat test

  The functional results of the single-leg squat test will be measured using the SIngle-leg squat Movement Performance scaLe for Individuals with FemoroAcetabular Impingement syndrome (SIMPLAI-FAI). The score on this scale ranges from 0 to 8. A higher score indicates a better functional outcome.

  Pre-intervention, at 3 months and 6 months post-intervention

• Measurements of patient-reported outcomes using the Hip-Return to Sport After Injury Scale (HIP-RSI)

  Analysis of scores obtained on the HIP-RSI questionnaire. This questionnaire assesses psychological readiness to resume sports activities following hip surgery. It consists of six items, and the final score ranges from 0 to 100. A higher score indicates greater psychological readiness to return to sports activities.

  Pre-intervention, at 3 months and 6 months post-intervention

• Measurements of patient-reported outcomes using the International Hip Outcome Tool-12 (iHot-12) questionnaire

  Analysis of scores obtained on the iHot-12 questionnaire. This questionnaire assesses the quality of life of young, active patients suffering from hip problems. It consists of 12 items and the final score ranges from 0 to 100. A score of 100 indicates full function and no symptoms, whereas a score of zero signifies maximum limitations and extreme symptoms.

  Pre-intervention, at 3 months and 6 months post-intervention

Study Arms (2)

Patient groups: 30 subjects with femoroacetabular impingement syndrome

Control group : 30 subjects with healthy hips

Eligibility Criteria

• Age: 18 Years - 40 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

Adults aged 18-40 years will be recruited. The patient group will include individuals diagnosed with femoroacetabular impingement syndrome who are scheduled to undergo hip arthroscopy by specialized surgeons. A healthy control group without a history of hip pathology will be recruited from the local community matched as closely as possible to the patient group for demographic parameters.

You may qualify if:

• Subjects with femoroacetabular impingement syndrome, with corresponding clinical symptoms and signs, as well as validation by imaging
• Subjects who have already consulted a surgeon specializing in hip arthroscopic surgery and whose surgery is planned to treat femoroacetabular impingement syndrome
• Subjects aged between 18 and 40

You may not qualify if:

• History of rheumatic disease, dysplasia or pediatric disease affecting the hip (Legg-Calvé; superior femoral epiphysiolysis)
• Subject who has already undergone surgery on the hip joint
• Subjects with a history of injury to the muscles involved in the assessments within the last year
